LINC00052, with previously unknown function, is significantly reduced in HER3-knockdown MCF7 breast cancer cells in comparison with the control cells as indicated by two independent probes (8.1 and 5.8 fold change of mRNA levels for probe 1 and probe 2, respectively, p ≤ 0.0001) (Figure 1B). This evidence concerns the gene ERBB3 and breast carcinoma.
